Abstract: An embodiment of the invention is directed to a relatively low cost technique for improving the sharpness or quality of digital images captured by a handheld portable media device. A housing of the device has integrated therein a digital camera image sensor, a camera lens, and a sensor that detects a distance measure, which is a measure of distance between the housing and an object or target in a scene that is before the lens. The device is programmed to select a point spread function, PSF, based on the detected distance measure. The selected PSF is then applied to de-blur the captured image, for becoming the final picture of the scene that is taken by the user. Other embodiments are also described and claimed.

Abstract: An electronic device may operate in standby and active modes. A headset may be coupled to the electronic device. The electronic device may have audio codec circuitry. The audio codec circuitry may use general purpose input-output circuitry in handling button and headset activity during active mode. Processing circuitry may be used to reconfigure the audio codec in real time. When the electronic device is in the standby mode and activity is detected, the codec may be configured to provide an interrupt signal to a power management unit that wakes the device. When the electronic device is in active mode and no user inputs are received within a given period of time, the central processor in the electronic device may place the device in standby mode.
